GPS GNSS Antenna

GPS (Global Positioning System) and GNSS (Global Satellite Navigation System) antenna is a device used to receive satellite signals for positioning and navigation. These antennas are vital components of modern navigation and positioning technology and can be used in numerous applications such as car navigation, aviation, marine and geographic surveying, etc.

The working principle of the positioning antenna is to use the radio frequency signal transmitted by the satellite, which is received and decoded by the antenna to determine the position and velocity of the receiver. In the receiving antenna, the radio-frequency signal passes through circuitry in the antenna, is converted to an electrical signal, and is picked up and decoded by the receiver to determine its position and velocity.

The performance of a positioning antenna is determined by factors such as its antenna gain, polarization, frequency range, and accuracy. Antenna gain is the strength of the signal received by the antenna, usually expressed in dBic (decibels relative to a theoretically equivalent equitropic spherical antenna) or dBd (decibels relative to a half-wavelength bicube antenna). Polarization refers to the signal polarization direction of the antenna, usually there are two kinds of vertical polarization and horizontal polarization. The frequency range refers to the frequency range of radio frequency signals that the antenna can receive, usually different frequencies such as L1, L2, and L5. Accuracy refers to the accuracy of antenna positioning and navigation, which can be further optimized by satellite receivers and positioning algorithms.
